Observation vs admission in syncope: can we predict short length of stays? Academic Article uri icon


  • Background Rising health care costs demands justifying prolonged hospitalization for syncope, yet predictors of shorter length of stay (LOS) have not been identified. Objective The objective of this study is to identify independent predictors of LOS for syncope patients presenting to the emergency department (ED). Methods We performed an analysis of a prospectively collected cohort of ED syncope patients. We examined risk factors from the patient's ED presentation and workup and used Spearman rank correlation to evaluate the relationship between these risk factors and LOS in a logistic regression model for prediction of hospitalization less than 1 day. Results Of 568 total syncope patients, 350 (61.6%) were admitted and comprise the study cohort. Mean age was 57 years (SD, ±25 years); 39.6% were male. Length of hospitalization was less than or equal to 1 in 179 patients (51.1%). The number of risk factors was associated with LOS ( P P Conclusion Patients with less than 1 predictor of prolonged stay, who present to the ED with syncope, are unlikely to require hospitalization of more than 1 day. A set of predictors may help define which patients are appropriate for 24-hour observation rather than full hospitalization.
